the hare, as it measures but seven inches, yet the similarity of the 

 coloring might at first mislead an observer into supposing it was 

 nothing more interesting, as its coat of grayish brown is the hare's 

 own hue and designed for the same purpose of protection among the 

 pika's gray rocks. A second glance would speedily detect, however, 

 the shorter hind legs, the close-set rounded ears, with their conspicu- 

 ous white edge, the absence of any external tail, all features which 

 distinguish it unmistakably from the true hare. 



In addition to the disguise afforded by its color, it has been 

 provided with soft hairy pads for its tiny feet that it may make 

 swift and sure progress over the slippery, and often icy, rocks, while 

 the brightness of its bead-like eyes are a true indication of its alert 

 and watchful disposition.
